当我用无水乙酸钠与碱石灰(市售)混和加热制取甲烷气体时,尽管严格按操作规程及实验步骤进行,但是仍会出现两个问题:一是实验中试管上方液滴太多,容易流到底部加热处,从而导致试管破裂;二是生成的甲烷气体量太少。后来,我又预先将碱石灰与无水乙酸钠分别放入电烘箱中烘烤,实验结果产生的水滴有所减少,但生成的甲烷气体量仍不够多。 When I use anhydrous sodium acetate and soda lime (commercially available) to mix and heat to produce methane gas, despite the strict implementation of the operating procedures and experimental procedures, there are still two problems: First, there are too many droplets above the test tube in the experiment. , easy to flow to the bottom of the heating, resulting in rupture of the test tube; second, the amount of methane gas generated is too small. Later, I preliminarily placed soda lime and anhydrous sodium acetate in an electric oven and baked them. The results showed that the amount of water droplets produced was reduced, but the amount of methane gas generated was still insufficient.
